Fig. 1. Microscopic findings at diagnosis and immunophenotypic features of the bone marrow aspirate by flow cytometric analysis at the first time. (A) Several pleomorphic immunoblastic large cells are evident on this bone marrow aspirate smear (red arrow) (Wright–Giemsa ×1,000). (B) The T-cells are positive for CD3 (shown in blue) with no skewing of the CD4: CD8 ratio. (C) The B-cells are positive for CD19 (shown in red) with surface lambda light chain restriction. (D) T-cell receptor (TCR) gene clonality assays for the patient’s bone marrow showed positive results.
